COOK, OF MILNAUKEE, "WSCONSIl RECE-D-DUSTNG BRUSH.

.application T all w hom t may concern Be it known that I, Louis E. Coon, a citizen of the United States, residing,- at lvlilwaukee. in the county of `ll/lilwaulree and State ot llf'riseonsin, have invented certain new and useful .improvements in lecord- Dusting` Brushes, ot which the following is a speciiication, reteremc being had to the accompanying drawings. l0 lt is well known that talking machine records, even though in cabinets or record racks, collect more or less dust. tinnen the record is played, the dust collects around the stylus, and therefore produces an interior reproduction of the record.

lt is, therefore, he purpose to provide a device ot the present character, tor ren'iov ing the dust Jfrom the :tace ot' the record while it is in the act of reproducing.

There are pads, which are manually operated, and others which are carried by the sound'box or reproducer, or by the tone arm. There are also brushes used on the reproducer or tone arm.

lt has been 'found that the brushes which are carried by the reproducer and by the tone arm are at all times operating' on the record, until the playing ot the record is completed. lt has also been discovered that the pads made of telt or other material merely sweep over the surface of the sound wave grooves, and do not enter the grooves.

rlherefore, it is another purpose to provide a brush manually actuated and adapted to sweep the entire record during one or two revolutions ot the record, and since the bristles are more or less pliable, their terminals will engage within the sound wave grooves, and thereby remove the dust and dirt, and no doubt, enable the record to be reproduced with a clear tone.

Also in devices which have heretofore been used the pad or brush is rigid with respect to the handle or with respect to the reproducer or tone arm, and for this reason the :telt or bristles will also sweep over the sound wave grooves., without entering the grooves.

Hence, a still further purpose consists in 5G the provision ot a brush, which is loosely mounted with respect to the handle, so that it can swirl or rotate in various positions as the record turns, in fact accommodate itself to the movement of the record, and since filed February 13, 1922.

Serial No. 536,204.

the brush is long,v enough to extend from where the sound wave groove begins to its extreme outer terminal groove, the record may be easily swept or cleaned in one, two or three revolutions ot the record.

-ulditionally the invention to provic e a brush ot this character, wherein the screw on which the handle swivelly mounted, is engaged through the handle, so that its head` will engage with the shoulder formed below the outer end ot the handle, so as to prevent detachment et the handle.

lt is also possible with the present form ot brush, to hold the brush stationary with respect to the handle by means ot the hand of the operator, and enable the brush to sweep the telt et the turntable. Furthermore the securing screw may be tight cned, so as to hold the wood portion ot the brush stationary with respect to the iandle, so to avoid the operator manually holding the brush stationary with respect to the handle, when sweeping` the turntable.

rhe brush, unlike those which are carried by the reproducer or tone arm, may be disposed, when not in use, in one corner et the top oit' the cabinet out ol' the way of the turntable, and in this case the brush is always handy, for the purpose of dustingthe records, or tor sweeping the face of the turntable.

Obviously the handle or the wood portion of the brush together with the bristles, or the screw may be easily renewed, by replac ing themwith others, thereby .avoiding the owner of a talking machine purchasing an entire new brush, when such is necessary.

l/Vhile the design and construction at present illustrated and set forth are deemed preferable, it is obvious that as a result of a reduction of the invention to a more practical form for commercial purposes, the invention may be susceptible of changes, and the right to these changes is claimed, provided they are comprehended within the scope of what is claimed.

The invention comprises further features and combination ot parts, as will be hereinafter set forth, shown in the drawings and claimed.

ln the drawings Figure l is a view, showing a record mounted on the turntable ot a talking; man

chine, and the brush held in position, for the purpose of brushing the grooves of the record;

Figure 2 is a longitudinal sectional view through the brush and the handle; and

Figure 3 is a cross sectional view on line 3-3 of Figure 2.

- Referring to the drawings, l designates the wood portion of the brush, which may be any suitable length, thickness or depth. ln tact the wood portion of the brush may be any proportions, preferably of a length to enable the brush to extend from where the sound. wave groove begins, to its terminal, or slightly further, in order that the iull surface of the sound wave groove, and space intermediate the grooves may be swept :in several revolutions, say for instance about three, more or less. The wood portion oi the brush may be any suitable shape, and the bristles 2 constructed ott any suitable hair, preferably camels hair, which is very light and soft, and which` will not naar, scratch or otherwise injure the sound wave grooves of 'the record.

A handle 3 is provided, and may be any suitable shape, length or diameter, preferably as shown. lThe handle has a bore il, through which an elongated screw 5 engages, and is threaded into the wood part ot' the brush. The outer' end of the bore of the handle is counter-sunk, thereby causing to be formed a. shoulder G, with respect to which the head T of the screw may be normally spaced. ln other words when holding the handle firm and the terminals of the bristles or' the brush are resting upon the record, the handle is held, so that there is a looseness ol play between the wood portion of the brush and the handle. For instance the handle will be held rni so as to enable the brush to easily and freely swirl with respect to the handle. @bviously the handle is swiveled on the brush, enabling the brush to :treely rotate while the handle is held iirrn in the operators hand. Ubviously the operator may grasp the handle, and a portion o'li the wood of the brush, and hold the two stationary with respect to each other, enabling the operator to hold the brush, whereby it may be used for sweeping the telt of the turntable. ln order to accomplish this result without the operator holdingthe wood portion oiI the brush with respect to the stationary portion of the handle, the screw may be tightened, so that the head of the Screw may tighten against the shoulder and hold the brush with respect to the handle. However, the brush is mounted to move freely with respect to the handle, or the handle swiveled with respect to the brush, and in this way enabling the brush to easily swirl, while the handle is held fastin the hand oit' the operator. In this way the brush is allowed to acconnnodate itseht` to the movement oit the record, enabling the terminals of the bristles to project into the grooves and thereby remove all the dust.

rlhe invention having been set forth, what is claimed is A record cleaning brush comprising a handle adapted to be grasped and held rigid in the hand of an operator, a brush body provided with a threaded socket and having bristles to sweep over and into the record grooves, said handle having a bore formed theretln'ough i'roin one end to the other, the outer end o' said bore being countersunk` a screw engaging through said bore loosely, whereby it may rock therein and having' its head engaging the bottom of the countersinlr at the outer end ol the bore, the shank ol' the screw having one end tapered and adj ustably connected within said threaded socket and adapted to be adjusted to hold the handle lixed relatively to the brush body7 or adjusted so that the screw may roclc or rotate in the bore, whereby the bristles may swirl with respect to the record, and allow the bristles to accommodate themselves to the record grooves.

ln testimony whereof l hereunto atlix my signature.
